BACKGROUND

The complete or partial detachment of ligaments, tendons and/or other soft tissues from their associated bones within the body are relatively commonplace injuries, particularly among athletes. Tissue detachment may occur as the result of an accident such as a fall, over-exertion during a work-related activity, during the course of an athletic event, or in any one of many other situations and/or activities.

In the case of a partial detachment, the injury will frequently heal itself, if given sufficient time and if care is taken not to expose the injury to further undue stress. In the case of complete detachment, however, surgery may be needed to re-attach the soft tissue to its associated bone or bones. Hip, shoulder, and rotator cuff repair procedures require the fastening of soft tissue to bone. Suture anchors provide one type of device that may be used in helping to re-attach soft tissue to its associated bone or bones.

In some embodiments, the first suturing system is configured for rotator cuff repair, bankart repair, slap lesion repair, biceps tenodesis, acromio-clavicular separation repair, deltoid repair, capsular shift, capsulolabral reconstruction, or any combination thereof of the shoulder. In some embodiments, the first suturing system is configured for lateral stabilization, medial stabilization, achilles tendon repair, hallux valgus reconstruction, mid-foot reconstruction, metatarsal ligament repair/tendon repair, bunionectomy, or any combination thereof of the foot. In some embodiments, the first suturing system is configured for lateral stabilization, medial stabilization, achilles tendon repair, hallux valgus reconstruction, mid-foot reconstruction, metatarsal ligament repair/tendon repair, bunionectomy, or any combination thereof of the ankle. In some embodiments, the first suturing system is configured for scapholunate ligament reconstruction, ulnar collateral ligament reconstruction, radial collateral ligament reconstruction, or any combination thereof of the hand. In some embodiments, the first suturing system is configured for scapholunate ligament reconstruction, ulnar collateral ligament reconstruction, radial collateral ligament reconstruction, or any combination thereof of the wrist. In some embodiments, the first suturing system is configured for biceps tendon reattachment, tennis elbow repair, ulnar or radial collateral ligament reconstruction, lateral epicondylitis repair, or any combination thereof of the elbow.

In some embodiments, the first suturing system comprises an anchor 400 and a suture inserter device 1000. In some embodiments, the anchor 400 comprises a suture 420 having a first end 421 and a second end 422, and an anchor insert 410. In some embodiments, the suture inserter device 1000 comprises a housing 100 and an inserter 200.

In some embodiments, the anchor insert 410 is coupled to the suture 420 between the first end 421 and the second end 422 of the suture 420. In some embodiments, the anchor insert 410 is coupled to a mesial portion of the suture 420. In some embodiments, the anchor 400 has an insertion configuration, per FIG. 4A, and a deployed configuration, per FIG. 4B. In some embodiments, the anchor 400 comprises one or more anchor inserts 410. In some embodiments, per FIG. 4C, the anchor 400 comprises a first anchor insert 410 a second anchor insert 410 and a link therebetween. In some embodiments, the link comprises the suture 420. In some embodiments, the anchor inserts comprise one or more knots formed with a different suture from suture 420 (e.g., an anchor insert suture), wherein the anchor inserts may additionally or alternatively be linked via the anchor suture itself. In some embodiments, the anchor 400 changes from a substantially linear configuration (e.g., FIG. 4A) in the insertion configuration to a substantially nonlinear configuration (e.g., FIG. 4B) in the deployed configuration of the anchor 400. In some embodiments, the first anchor insert 410 is coupled to the second anchor insert 410 and is disposed serially between the first end 421 and the second end 422 of the suture 420 when the anchor 400 is in the insertion configuration. In some embodiments, at least two anchor inserts 410 are coupled to each other. In some embodiments, at least one anchor insert 410 is individually coupled to the suture 420. In some embodiments the plurality of anchor inserts 410 are substantially linear when the anchor 400 is in the insertion configuration to enable insertion within a bone hole or other tissue aperture. For example, as shown in some embodiments, the anchor inserts 410 are provided in a row when the anchor 400 is in the insertion configuration. In some embodiments, per FIG. 4B, the plurality of anchor inserts 410 are substantially non-linear when the anchor 400 is in the deployed configuration such that the anchor inserts 410 interlock within a bone hole (e.g., 402) or other tissue aperture. For example, as shown in FIG. 4B, in some embodiments, the anchor inserts 410 are provided in two or more rows when the anchor 400 is in the deployed configuration. In some embodiments, the anchor inserts 410, when in the deployed configuration, are arranged in any orientation and sequence with respect to each other. For example, FIG. 3B depicts the deployed configuration of the anchor inserts in two rows and two columns, with each anchor insert aligned with another anchor insert in the corresponding row or column. FIG. 4B depicts the deployed configuration with two rows of the anchor inserts, wherein the anchor inserts are not aligned in a column. In some embodiments, the anchor inserts, when in a deployed configuration, are arranged in a manner that resembles a diamond shape. Further, in some embodiments, the first end of the suture 421 is proximal to at least a portion of the anchor insert 410 when the anchor 400 is in the insertion configuration. In some embodiments, the suture 420 is referred to as a repair suture herein.

In some embodiments, per FIG. 4C, the width 430C of any one anchor insert 410 is from about 0.1 mm to about 10 mm. In some embodiments, the width 430C of each individual anchor insert 410 is at most about 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1 mm, including increments therein. In some embodiments, the width 430C of each individual anchor insert 410 is at least about 0.1, 1, 2, 3, 4, 5, 6, 7, 8, or 9 mm, including increments therein. In some embodiments, the outer width 430C of the anchor insert 410 is from about 0.1 mm to about 10 mm, or is at most about 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1 mm, including increments therein. In some embodiments, the outer width 430C of the anchor insert 410 is from about 0.1 mm to about 10 mm, or is about 0.1, 1, 2, 3, 4, 5, 6, 7, 8, or 9 mm, including increments therein. Accordingly, in some embodiments, the outer width 430C of the anchor 400 in the insertion configuration (e.g., when the anchor is in a linear or substantially linear configuration) enables the anchor 400 to be inserted within the bone hole (e.g., 402) or other tissue aperture. As discussed herein, in some embodiments, the outer width 430A of the anchor inserts 410 (together) in the insertion configuration is configured to be approximately the outer width 430C, thickness, or diameter 430C of an individual anchor insert 410. In some embodiments, the outer width 430A of the anchor inserts 410 (together) in the insertion configuration corresponds to a lateral dimension relative to a longitudinal length of the anchor insert 410. In some embodiments, the outer width 430A of the anchor inserts 410 (together) in the insertion configuration is greater than, the same, or substantially the same diameter or width as a bone hole. Accordingly, in some embodiments, the anchor in the insertion configuration contacts the inner walls of a bone hole (as depicted in FIG. 4A). In some embodiments, the anchor in the insertion configuration provides a tight-fit or snug-fit interaction with the inner wall of the bone hole.

In some embodiments, the anchor 400 is configured to transition from the insertion configuration to a deployed configuration. In some embodiments, the deployed configuration comprises displacing the anchor inserts 410 such that the outer width 430B of the anchor inserts 410 (together) in the deployed configuration, along a lateral dimension compared to a longitudinal direction of a bone hole (e.g., FIG. 4B), is greater than the outer width 430A of the anchor inserts 410 (together) when the anchor 400 is in the insertion configuration. For example, in some embodiments, the plurality of anchor inserts 410 are aligned in two or more rows when the anchor 400 is in the deployed configuration (e.g., FIG. 4B). Accordingly, the outer width 430B of the anchor inserts 410 (together) in the deployed configuration with two rows (FIG. 4B) is greater than the outer width 430A of the anchor inserts 410 (together) arranged in one row (FIG. 4A). In some embodiments, the outer width 430C of the anchor 400 is measured as an outer diameter or an outer thickness. As described herein, in some embodiments, the anchor inserts is configured to push at least a portion of the inner wall defining a bone hole when transitioning from the insertion configuration to the deployed configuration (see FIG. 4B for example).

In some embodiments, the outer width 430A of the anchor inserts 410 (together) in the insertion configuration is greater than, the same, or substantially the same diameter or width as a bone hole. Accordingly, in some embodiments, in some embodiments, the anchor inserts 410 in the insertion configuration contacts the inner walls of a bone hole. In some embodiments, the anchor inserts 410 in the insertion configuration provide a tight-fit or snug-fit interaction with the inner wall of the bone hole. Accordingly, in some embodiments, transitioning the anchor from an insertion configuration to a deployed configuration results in the anchor inserts pushing against the inner walls of the bone hole (for example, see FIG. 4B). In some embodiments, the anchor inserts in the deployed configuration push the bone hole walls to accommodate having a substantially non-linear configuration. For example, in some cases, the anchor inserts contact an inner wall of the bone hole that can be articulated to allow the anchor inserts extend at least partially beyond a bone hole width (e.g., see FIG. 3B, 4B). In some cases, the inner wall includes a thickness (e.g., 404) that is at least partially malleable, as opposed to a portion of the bone beyond said thickness, which may be more dense and thus more difficult to for the anchor inserts to push when transitioning to a deployed configuration (e.g., cortical region of bone).

Accordingly, in some embodiments, when the one or more anchor inserts 410 are arranged in a substantial linear configuration in the insertion position, the outer width 430A of the anchor inserts 410 (together), along a lateral dimension compared to a longitudinal direction of a bone hole (e.g., FIG. 4A), is from about 0.1 mm to about 10 mm. In some embodiments, the outer width 430C of the one or more anchor inserts 410 is greater than an inner diameter of an inserter lumen (e.g., see 210 in FIG. 4A/4B). Accordingly, in some embodiments, the one or more anchor inserts will abut the walls of the inserter 200 (e.g., when the inserter fork 230 is retracted into inserter lumen 210).

In some embodiments, the outer diameter 430B of the anchor inserts 410 (together) in the deployed configuration is greater than a diameter of a bone hole, an opening to the bone hole, and/or an opening to a tissue as described herein (where a surgical procedure is being performed). Accordingly, in some embodiments, the anchor inserts 410 when the anchor 400 is in the deployed configuration are pressed against an inner wall of a bone wall, thereby providing tension of the suture 420. Accordingly, in some embodiments, after the anchor 400 has been inserted within a bone hole opening or tissue opening in the insertion configuration, the pull out strength of the anchor 400 (i.e. a force required to pull the anchor 400 out through the bone hole opening or tissue opening) significantly increases in the deployed configuration as compared to the insertion configuration. In some embodiments, the pull out strength of the anchor 400 in the deployed configuration within a bone hole is from about 5 psi to about 40 psi. In some embodiments, the pull out strength of the anchor 400 within a bone hole is from about 15 psi to about 25 psi.

In some embodiments, one or more anchor inserts 410 have a shape comprising a circle, sphere, a cylinder, a pyramid, a torus, a cone, a prism, or any combination thereof. In some embodiments, one or more anchor inserts 410 is a suture 420 knot. In some embodiments, one or more anchor inserts 410 comprise knots in a suture different from suture 420 (as described herein, for e.g., see anchor suture). In some embodiments, one or more of the anchor inserts 410 comprise a hollow structure. In some embodiments, the suture 420 passes through each of the hollow structures of such anchor inserts 410 (e.g., FIGS. 4A-4C). In some embodiments, one or more of the anchor inserts 410 comprise a solid structure (e.g., FIGS. 4A-4C). In some embodiments, the suture 420 is affixed to each of the solid structures of such anchor inserts 410. In some embodiments, each of the solid structures of the anchor inserts 410 are tethered to a common loop that is also coupled to the suture 420, thereby operatively coupling the suture 420 to said anchor inserts 410. In some embodiments, the one or anchor inserts 410 comprise one or more knots of the suture 420 or another suture (as described herein). In some embodiments, the one or more anchor inserts 410 comprise suture 420 balls, or other balls. In some embodiments, the one or more anchor inserts 410 comprise cylindrical, oval and/or disk shapes. In some embodiments, for any anchor herein, the anchor inserts 410 comprise any shape, such as spherical, cylindrical, oval, disk, triangular, square, or any non-uniform shape.

In some embodiments, the depth of a bone hole required to be drilled is at least partially dependent on the number of anchor inserts 410 on the anchor 400. In some embodiments, increasing the number of anchor inserts 410 provides an increased pull out strength of the anchor 400 when in the deployed configuration. In some embodiments, reducing the number of anchor inserts 410 in the anchor 400 reduces or limits the depth of the bone hole needed to contain the anchor inserts 410. In some embodiments, the number of anchor inserts 410 in the anchor 400 is optimized depending on the anatomical portion being targeted, so as to balance the required bone drill depth and pull out strength. In some embodiments, the plurality of anchor inserts 410 comprises 3, 4, 5, 6, 7, 8 or more anchor inserts 410. In some embodiments, the depth of the bone hole using a suturing system described herein is from about 10 mm to about 30 mm. For example, in some embodiments, the depth of the bone hole using a suturing system comprising four anchor inserts 410 for a shoulder/hip labral repair is about 15 mm to about 20 mm, or less. In another example, in some embodiments, the depth of the bone hole using a suturing system comprising four anchor inserts 410 for a rotator cuff repair is about 22 mm to about 28 mm, or less. In some embodiments, the outer width of the anchor insert 410 is greater than the drill diameter of the bone hole, which may be at most about 2-4 mm for a shoulder/hip labral repair. In another example, the outer width of the anchor insert 410 is greater than the drill diameter of the bone hole, which may be at most about 3-5 mm for a shoulder/hip labral repair.

FIG. 22 depicts another exemplary embodiment of an anchor 2200 having been configured for any suturing system described herein. In some embodiments, the anchor comprises a plurality of anchor inserts 2210. In some embodiments, the anchor 2200 comprises two sutures 2220, 2222, that form the one or more anchor inserts 2210. In some embodiments, the two sutures 2220, 2222 are configured to form a loop 2202 or chain between the anchor inserts 2210. In some embodiments, the anchor 2200 is arranged in a braided configuration. In some embodiments, one or both distal ends 2224, 2226 of each suture 2220, 2222 is configured to be weaved back through (not shown) one or more loops 2202 between each anchor insert 2210. In some embodiments, pulling on one or both of the distal ends 2224, 2226 after being weaved through the one or more loops 2202 allows the anchor to transition from an insertion configuration to a deployed configuration. In some embodiments, the anchor 2200 comprises a single suture.

FIGS. 23A-23C depict another exemplary embodiment of an anchor 2300 having been configured for any suturing system described herein. In some embodiments, the anchor 2300 does not include an anchor insert having an fixed central opening. In some embodiments, the anchor 2300 may include one or more anchor inserts 2310 that can allow a repair suture 2320 (for example) to weave through, as shown in FIG. 23B. In some embodiments, the repair suture 2320 weaves through the anchor inserts (which may comprises “suture knots” on a separate suture). In some embodiments, the repair suture 2320 passes through the anchor inserts (e.g., through the actual inserts or knots). In some embodiments, the repair suture 2320 weaves past at least some of the anchor inserts, but is passed through the most distal anchor insert (e.g., anchor insert located furthest from a bone hole opening). In some embodiments, the repair suture 2320 is disposed within an inserter, such that when the repair suture 2320 has been inserted through one or more inserts (e.g., knots) 2310, the repair suture 2320 can be pulled so as to transition the anchor 2300 from an insertion configuration to the deployed configuration, as shown in FIG. 23C.

For any embodiment herein, the anchor insert (e.g., 410, 1910, 2210, 2310, etc.) may be of any shape. For example, the anchor insert for any embodiment of an anchor described herein may be spherical, round, oval, ellipsoidal, rectangular, square, triangular, polygonal, or any combination thereof.

For any embodiment of an anchor (e.g., 400, 1900, 2200, 2300) described herein, the anchor may be manufactured according to any automated process known in the art. For example, the anchor may be manufactured using a braiding machine. In some embodiments, for any embodiment of anchor described herein, the anchor may be at least partially manufactured by hand.

With reference to FIG. 1 , FIGS. 3A-3B, and FIGS. 5A-5C, in some embodiments, the suture inserter device 1000 comprises a housing 100, an inserter 200, and/or an inserter fork 230. As used herein, the term “inserter” (for e.g., ref. char. 200) and the term “driver” may be used interchangeably. In some embodiments, the housing comprises a housing shaft axially translatable within a housing lumen 110. In some embodiments, the inserter 200 is coupled to the housing shaft 250. In some embodiments, the inserter 200 is axially translatable within the housing lumen 110. In some embodiments, the inserter 200 is axially translatable within the housing lumen 110 via translation of the housing shaft 250. In some embodiments, the inserter 200 is axially translatable within the housing lumen 110 between a distal position and a proximal position. In some embodiments, a distal portion of the inserter 200 is configured to extend from the housing lumen 110. In some embodiments, the inserter 200 comprises an inserter lumen 210 extending at least partially therethrough. In some embodiments, the inserter fork 230 (see FIG. 5C) is disposed within the inserter lumen and configured to extend from the inserter lumen. In some embodiments, the inserter fork 230 is coupled to the housing shaft 250, and is disposed within an inserter lumen. In some embodiments, the insert fork 230 is axially translatable within the inserter lumen 210 and the housing lumen 110. In some embodiments, the inserter fork 230 is axially translatable via the housing shaft 250 and within the inserter lumen 210 inserter 200, wherein the inserter 200 and the inserter lumen 210 are not axially translatable.

In some embodiments, the first end 421 and/or the second end 422 of the suture 420 is coupled to the inserter 200. In some embodiments, an outer surface of the housing shaft 250 comprises a threaded portion 240 configured to engage with a complimentary inner surface of the housing lumen. In some embodiments, the suture inserter device 1000 comprises a handle 300 a proximal end thereof. In some embodiments, the handle 300 comprises a knurl, a knob, a textured surface, or any combination thereof. In some embodiments, the handle 300 is configured to rotate, thereby axially translating the housing shaft 250 and therefore inserter 200. In other embodiments, the handle 300 is configured to rotate, thereby axially translating the housing shaft 250 and therefore the inserter fork 230 within the inserter lumen 210. In some embodiments, the handle 300 and/or the housing 100 rotate relative to the inserter 200. In some embodiments, the housing shaft 250 rotates relative to the handle 300 and the housing 100.

In other embodiments, the handle 300 is configured to rotate and tighten the suture 420 (e.g., tension the suture). In some embodiments, the inserter fork 230 is configured to be retracted and axially translated within the inserter lumen 210 via the housing shaft 250 being pulled back (e.g., manually pulling back the housing shaft 250).

In some embodiments, the housing 100 shaft has a housing 100 threaded portion, wherein the inserter 200 has an inserter 200 threaded portion, and wherein the inserter 200 is axially translatable with respect to the housing lumen 110 by rotating the housing's 100 threaded portion with respect to the inserter's 200 threaded portion.

In some embodiments, per FIGS. 4A, 4B, and 5C, the inserter 200 comprises a suture channel opening 220 accepting the first end 421 and the second end 422 of the suture 420. In some embodiments, as shown, the first end 421 and the second end 422 of the suture 420 enter and/or exit the inserter lumen 210 via suture channel opening 220, such that a practitioner can apply a tensile force to the first end 421 of the suture 420, the second end 422 of the suture 420, or both. In some embodiments, a distal tip of the inserter 200 comprises an inserter fork 230 receiving an anchor insert 410 (e.g., the distal anchor inserts 410). Accordingly, in some embodiments, the anchor inserts 410 are placed within a bone hole using the inserter fork. Alternatively, in some embodiments, a distal tip of the inserter 200 comprises a channel sized to hold the suture 420 and the anchor inserts 410.

In some embodiments, the suture 420, the anchor 400, the housing 100, the housing shaft 250, the inserter 200, or any combination thereof are formed of metal, plastic, glass, wood, ceramic, or any combination thereof.

With reference to FIGS. 5A-5C, in some embodiments, the first suturing system further comprises a deployment suture 423. In some embodiments, the deployment suture 423 is configured to be linked with a leading anchor insert 410 (for example the anchor insert 410 entering through a bone hole or suture 420 opening first (see e.g., FIG. 4A). In some embodiments, the deployment suture 423 is disposed within the inserter 200, such that when the anchor insert 410 has been inserted through the bone hole or tissue opening, the deployment suture 423 can be pulled so as to transition the anchor 400 from an insertion configuration to the deployed configuration. In some embodiments, continued pulling on the deployment suture 423 separates it from the leading anchor insert 410, and optionally, the deployment suture 423 may then be removed.

First Suturing System—Knotless Version

In some embodiments, the first suturing system is provided as a knotless embodiment, such that two ends of a suture need not be knotted together to secure a suture between two bone segments, a bone segment and a tissue segment, and/or two tissue segments. FIGS. 19A-B depict an exemplary configuration of a suture anchor 1900, comprising a repair suture 1920 and one or more anchor inserts 1910. In some embodiments, the anchor inserts 1910 are coupled to the repair suture 1920. In some embodiments, the anchor inserts 1910 are formed of the repair suture 1920 (e.g., the repair suture is knotted along its length to form an anchor insert, wherein a plurality of “knots” (as described herein) correlates to a plurality of anchor inserts). In some embodiments, the anchor inserts 1910 are a separate component from the repair suture 1920, and configured to be attached or otherwise coupled to a first end or about a first end of the repair suture 1920. For example, in some embodiments, the anchor inserts comprise one or more knots formed with a different suture from repair suture 1920 (e.g., an anchor insert suture), wherein the anchor inserts may additionally or alternatively be linked via the anchor suture itself. As used herein, about a first end refers to either located at the first end, or a distance from the first end that is about 0.1% to 50% of the total length of the repair suture 1920. Accordingly, where the anchor inserts are located a distance from the first end of the repair suture, this refers to all the anchor inserts being located between the first end and a second of the repair suture 1920. In some embodiments, the suture anchor 1900 is inserted within a bone hole, similar to as depicted in FIGS. 4A-C.

In some embodiments, a terminal anchor insert (e.g., 1910 a) is located at a first end of the repair suture 1920 or about a first end of the repair suture 1920 (as described herein). In some embodiments, similar to as depicted in FIGS. 4A-C, as described herein, the anchor 1900 is inserted within the bone hole in an insertion configuration, as seen in FIGS. 19A-B. In some embodiments, the anchor 1900 is inserted within the bone hole similar to as described in FIGS. 4A-5C. In some embodiments, the terminal anchor insert (e.g., 1910 a) is located closest to the bone hole opening when the anchor 1900 is inserted in the insertion configuration.

In some embodiments, a second end 1921 of the repair suture (e.g., opposite from the first anchor insert 1910 a) is weaved through anchor inserts 1910 (as depicted in FIG. 19B). Accordingly, in some embodiments, the second end 1921 of the repair suture 1920 is configured to be pulled away from the bone hole, thereby enabling the second end 1921 of the repair suture to be inserted through another bone segment and/or a tissue segment. In some embodiments, where the repair suture 1920 is coupled to the anchor inserts and/or forms one or more of the anchor inserts (e.g., via “knots” along the length of the repair suture), pulling the second end 1921 away from the bone hole transitions the anchor 1900 from an insertion configuration to a deployed configuration, thereby securing a portion of the repair suture 1920 within the bone hole (as described herein, which may be for a first bone segment).

In some embodiments, the repair suture 1920 is inserted into a bone hole with a passing suture. For example, FIGS. 20A-B depict an anchor comprising a repair suture 1920, as described herein, with a passing suture 1930. In some embodiments, the repair suture 1920 comprises a hollow interior at least along a portion therein, wherein the passing suture 1930 is configured to be inserted through a portion of the hollow interior of the repair suture 1920. In some embodiments, the repair suture 1920 comprises two openings 1922, 1923 along its length, such that the passing suture 1930 is inserted through one opening (e.g., 1922) and comes out another opening (e.g., 1923). In some embodiments, the distance between the two openings 1922, 1923 is from about 0.2 mm to about 45 mm, from about 0.5 mm to about 30 mm, from about 0.7 mm to about 25 mm, from about 1.0 mm to about 20 mm, from about 1.5 mm to about 15 mm, or from about 2 mm to about 10 mm. In some embodiments, the repair suture 1920 comprises a #2 suture. In some embodiments, the passing suture 1930 comprises a #2-0 suture. In some embodiments, the passing suture 1930 comprises a suture loop 1932 at a primary end of the passing suture 1930, which is opposite a secondary end 1931 of the passing suture 1930. In some embodiments, as described herein, the passing loop is at least partially located within the hollow interior, wherein the primary end 1932 extends from a first opening (e.g., 1922), while the secondary end 1931 extends from the second opening (e.g., 1923). In some embodiments, the passing loop 1932 is configured to receive and couple with the second end 1921 of the repair suture 1920, such that pulling on the secondary end 1931 of the passing suture 1930 also pulls the second end 1921 of the repair suture 1920 (e.g., via its coupling with the passing loop 1932), and thereby allows the second end 1921 of the repair suture 1920 to be pulled through a first opening (e.g., 1922) of said repair suture 1920 to the hollow interior (as described herein), through the hollow interior of the repair suture 1920, and then out a second opening (e.g., 1923), such that a portion of the repair suture 1920 is inserted within itself within the hollow interior. FIG. 21 depicts an exemplary anchor (in the deployed configuration) wherein the second end 1921 of the repair suture passed through the hollow interior of the repair suture 1920 (between the two openings 1922, 1923), such that a portion of the repair suture 1920 remains within the hollow interior portion 1924. In some embodiments, the portion of the repair suture within the hollow interior portion 1924 is held in place due to the friction therein (e.g., outer wall of portion of repair suture contacting inner wall of hollow interior of the repair suture), that helps prevent the portion of the repair suture from sliding out of the hollow interior portion 1924 (e.g., helps prevent the second end 1921 of the repair suture moving back towards the opening 1923). In some embodiments, such configuration of securing the repair suture within itself (in the hollow interior) allows the repair suture 1920 to secure a bone segment (via the anchor inserts 1910 in the bone hole) with a tissue and/or other bone segments (via the repair suture being inserted through said tissue and/or other bone segments, and back to the bone hole and through the hollow interior).

In some embodiments, the anchor 700 comprises a suture 720, a first anchor 700A, and a second anchor 700B. In some embodiments, the first anchor 700A is coupled to a distal portion of the suture 720 and the second anchor 700B is coupled to the suture 720 proximal to the first anchor 700A. In some embodiments, the suture inserter device 2000 comprises a housing 500 and a second needle 620 and a second housing lumen 520. In some embodiments, the housing 500 comprises a first needle 610. In some embodiments, the first anchor 700A couples to the second needle 620. In some embodiments, the first needle 610 receives a portion of the suture 720 proximal to the first anchor 700A and distal to the second anchor 700B. In some embodiments, the second needle 620 is axially translatable within the second housing lumen 520 between a primary configuration and a secondary configuration. With reference to FIG. 7C, in some embodiments the second housing lumen is disposed within the housing 500. As shown in FIG. 17A, in some embodiments a needle described herein comprises a distal end with a step 622, wherein the anchor inserts are placed at the distal end.

In some embodiments, per FIG. 8 , the first anchor 700A comprises a plurality of first anchor inserts 710A, and the second anchor 700B comprises a plurality of second anchor inserts 710B. In some embodiments, each of the plurality of first anchor inserts 710A is coupled to a preceding first anchor insert 710A, a subsequent first anchor insert 710A, or both. In some embodiments, each of the plurality of first anchor inserts 710A is coupled to a preceding first anchor insert 710A, a subsequent first anchor insert 710A, or both by a first link 731. In some embodiments, each of the plurality of second anchor inserts 710B is coupled to a preceding second anchor insert 710B, a subsequent second anchor insert 710B, or both. In some embodiments, each of the plurality of second anchor inserts 710B is coupled to a preceding second anchor insert 710B, a subsequent second anchor insert 710B, or both by a second link 732. In some embodiments, the first link 731, the second link 732, or both are formed of the same materials as the suture 720. In some embodiments, one or more of the first anchor inserts 710A, one or more of the second anchor inserts 710B, or both have a cavity therein. In some embodiments, the first link 731, the suture 720, or both pass through the cavity of one or more of the plurality of first anchor inserts 710A. In some embodiments, the first link 731, the suture 720, or both freely pass through the cavity of one or more of the plurality of first anchor inserts 710A. In some embodiments, the second link 732, the suture 720, or both pass through the cavity of one or more of the plurality of second anchor inserts 710B. In some embodiments, the second link 732, the suture 720, or both freely pass through the cavity of one or more of the plurality of second anchor inserts 710B. Further, as shown, in some embodiments, at least a portion of the suture 720 passes through a loop formed by the first link 731, the second link 732, or both. In some embodiments, at least two of the plurality of first anchor inserts 710A are coupled, wherein at least two of the plurality of first anchor inserts 710A inserts are coupled, or both. In some embodiments, at least two of the plurality of first anchor inserts 710A inserts are separate, wherein at least two of the plurality of first anchor inserts 710A are decoupled, or both. In some embodiments, per FIG. 6C, the plurality of first anchor inserts 710A couple to the second needle 620, wherein the plurality of second anchor inserts 710B couple to the first needle 610. Alternatively, in some embodiments, the plurality of first anchor inserts 710A couple to the first needle 610, wherein the plurality of second anchor inserts 710B couple to the second needle 620.

In some embodiments, at least a portion of the plurality of first anchor inserts 710A, plurality of second anchor inserts 710B, or both, have a shape comprising a sphere, a cylinder, a pyramid, a torus, a cone, a prism, or any combination thereof. For example, per FIG. 7C the suture 720 may run through the first anchor inserts 710A and/or the second anchor inserts 710B twice to create a suture one way lock. In some embodiments, at least a portion (e.g., a first anchor insert per FIG. 7C) of the plurality of first anchor inserts 710A and/or the plurality of second anchor inserts 710B may attach to the end of the suture while the remaining portions of the first anchor inserts 710A or second anchor inserts 710B moving freely. In some embodiments, at least a portion of the plurality of first anchor inserts 710A, plurality of second anchor inserts 710B, or both, comprise 3, 4, 5, 6, 7, 8 or more anchor inserts 710A 710B. In some embodiments, the anchor inserts comprise one or more knots formed with a suture separate from the suture 720 (e.g., anchor suture, as described herein), wherein the link between the anchor inserts is the anchor suture itself.

In some embodiments, the second needle 620 is axially translatable within the second housing lumen 520 between a primary configuration, per FIGS. 6A and 7A, and a secondary configuration, per FIGS. 6B and 7B. In some embodiments, in the primary configuration, a distal point of the second needle 620 is proximal to a distal point of the first needle 610.

In some embodiments, the suture 720 comprises a repair suture and a separate deployment suture is used to transition the anchor 700 from an insertion configuration to a deployed configuration.

Method of Anchoring to a Bone

Another aspect provided herein is a method of anchoring to a bone, the method comprising: providing the first suturing system; inserting the inserter and the anchor into a hole in the bone; applying tension to the second end of the suture to alter the anchor from the insertion configuration to the deployed configuration; and axially translating the inserter with respect to the housing shaft from the distal position to the proximal position. In some embodiments, instead of applying tension to the second end of the suture, a deployment suture is provided and pulled to transition the anchor from an insertion configuration to a deployed configuration.

In some embodiments, the method further comprises trimming the suture, tightening the suture, locking the suture, or any combination thereof. In some embodiments, the hole in the bone has a depth of less than about 35 mm. In some embodiments, the hole in the bone has an inner diameter of less than about 5 mm. In some embodiments, an outer diameter of the housing is greater than the inner diameter of the hole. In some embodiments, the inserter is configured to enter at least partially within the bone hole.

In some embodiments, a method for inserting a suture for anchoring a soft tissue to a bone comprises providing a suture inserter device (e.g., first suturing system as described herein) having an anchor comprising a suture and one or more anchor inserts coupled to an inserter (as used herein, the term “inserter” and “driver” may be used interchangeably). In some embodiments, the inserter is in the distal position (e.g., FIG. 3A), such that the distal portion of the inserter extends from the housing shaft. In some embodiments, the anchor inserts are placed within the bone hole via an inserter fork 230 (as described herein). In some embodiments, the anchor inserts are placed within the bone hole in the insertion configuration. In some embodiments, the inserter is placed against the bone, wherein the inserter with the suture and anchor insert are inserted within the bone hole, wherein the anchor insert is in the insertion configuration (see FIG. 3A). In some embodiments, a deployment suture is provided, coupled to a leading anchor insert (e.g., anchor insert located deepest within the bone hole in FIG. 4A), wherein the deployment suture is configured to be pulled, and further configured to pull on the leading anchor insert, thereby transitioning the anchor from an insertion configuration to a deployed configuration. In some embodiments, one end of a suture is tensioned, or both ends of a suture are tensioned, so as to pull on the anchor inserts and transition the anchor from an insertion configuration to a deployed configuration. In some embodiments, the inserter fork is axially translatable, and configured to be retracted, for example into the inserter lumen 210, wherein the anchor inserts are configured to abut inserter 200 walls and thereby transition from an insertion configuration into a deployed configuration. In some embodiments, any one of the aforementioned methods for transitioning the anchor from an insertion configuration to a deployed configuration, either alone or in combination with another method, is used to transition the anchor from an insertion configuration to a deployed configuration.

In some embodiments, the inserter is axially translated proximally (i.e. out of the bone hole), as described herein). In some embodiments, the suture may be tensioned prior to and/or after the inserter has been axially translated.

In some embodiments, as the inserter is being axially translated out of the bone hole, it pulls on an end of the suture, such that the leading anchor insert (e.g., the anchor insert located deepest within the bone hole in FIG. 4A) is then pulled by the end of the suture being pulled, thereby transitioning the anchor insert from an insertion configuration to a deployed configuration (e.g., FIG. 4B). In some embodiments, the inserter continues to pull on the suture so as to tension the suture, and thereby further enabling the anchor insert to be in the deployed configuration.

In some embodiments, such a method provides an example of a suture secured by tying the two ends of the suture in a knot once passed through a respective tissue or other bone. In some embodiments, as described herein (see e.g., FIG. 19 as described herein), a knotless suture anchor insert may be used. In some embodiments, the inserter is initially in the proximal portion (e.g., FIG. 4B), and is translated into the distal position once the inserter is placed against the bone.

Method of Anchoring to a Bone Using a Knotless Suture Anchor System

Another aspect provided herein is a method of anchoring to a bone using a knotless suture system as described herein. With reference to FIGS. 19-21 , the method comprises: providing a suture anchor 1900 with a passing suture 1930; inserting the inserter and the anchor 1900 into a hole in the bone; applying tension to the second end 1921 of the repair suture 1920 to alter the anchor 1900 from the insertion configuration to the deployed configuration; and axially translating the inserter with respect to the housing shaft from the distal position to the proximal position (as described herein). In some embodiments, applying tension to the second end 1921 of the repair suture comprises pulling the second end of the repair suture away from the bone hole. In some embodiments, instead of applying tension to the second end 1921 of the suture, a deployment suture is provided and pulled to transition the anchor from an insertion configuration to a deployed configuration.

In some embodiments, the method further comprises inserting the second end 1921 of the repair suture through a target tissue or a target bone; returning the second end 1921 of the repair suture towards the bone hole; coupling the second end 1921 with the suture loop 1932 of the passing suture 1930; tensioning (e.g., pulling) the secondary end 1931 of the passing suture 1930, such that the passing loop 1932 and second end 1921 of the repair suture are pulled within and then out of the repair suture 1920 (via the openings 1922, 1923); separating the second end 1921 of the repair suture from the suture loop 1932 (optionally outside the bone hole); and pulling to desired tension on the second end 1921. Accordingly, the repair suture 1920 is now secured within the bone hole, itself, and with a target tissue segment or target bone segment (due to the tension/friction of the repair suture within a hollow interior of itself, as described and depicted in FIGS. 20-21 herein).

In some embodiments, the method further comprises trimming the repair suture, tightening the repair suture, locking the repair suture, or any combination thereof. In some embodiments, the hole in the bone has a depth of less than about 35 mm. In some embodiments, the hole in the bone has an inner diameter of less than about 5 mm. In some embodiments, an outer diameter of the housing is greater than the inner diameter of the hole. In some embodiments, the inserter is configured to enter at least partially within the bone hole.

In some embodiments, a method for inserting a suture for anchoring a soft tissue to a bone comprises providing a suture inserter device (for e.g., first suturing system as described herein) having an anchor comprising a suture and one or more anchor inserts coupled to an inserter (as used herein, the term “inserter” and “driver” may be used interchangeably). In some embodiments, the inserter is in the distal position (e.g., FIG. 3A), such that the distal portion of the inserter extends from the housing shaft. In some embodiments, the anchor inserts are placed within the bone hole via an inserter fork 230 (as described herein). In some embodiments, the anchor inserts are placed within the bone hole in the insertion configuration. In some embodiments, the inserter is placed against the bone, wherein the inserter with the suture and anchor insert are inserted within the bone hole, wherein the anchor insert is in the insertion configuration (see FIG. 3A). In some embodiments, a deployment suture is provided, coupled to a leading anchor insert (e.g., anchor insert located deepest within the bone hole in FIG. 4A), wherein the deployment suture is configured to be pulled, and further configured to pull on the leading anchor insert, thereby transitioning the anchor from an insertion configuration to a deployed configuration. In some embodiments, one end of a suture is tensioned, or both ends of a suture are tensioned, so as to pull on the anchor inserts and transition the anchor from an insertion configuration to a deployed configuration. In some embodiments, the inserter fork is axially translatable, and configured to be retracted, for example into the inserter lumen 210, wherein the anchor inserts are configured to abut inserter 200 walls and thereby transition from an insertion configuration into a deployed configuration. In some embodiments, any one of the aforementioned methods for transitioning the anchor from an insertion configuration to a deployed configuration, either alone or in combination with another method, is used to transition the anchor from an insertion configuration to a deployed configuration.

In some embodiments, the inserter is axially translated proximally (i.e. out of the bone hole), as described herein). In some embodiments, the suture may be tensioned prior to and/or after the inserter has been axially translated.

In some embodiments, as the inserter is being axially translated out of the bone hole, it pulls on an end of the suture, such that the leading anchor insert (e.g., the anchor insert located deepest within the bone hole in FIG. 4A) is then pulled by the end of the suture being pulled, thereby transitioning the anchor insert from an insertion configuration to a deployed configuration (e.g., FIG. 4B). In some embodiments, the inserter continues to pull on the suture so as to tension the suture, and thereby further enabling the anchor insert to be in the deployed configuration.

In some embodiments, a knotless suture anchor insert may be used as described herein for any inserter described herein (see e.g., FIGS. 19-21 as described herein). In some embodiments, the inserter is initially in the proximal portion (e.g., FIG. 4B), and is translated into the distal position once the inserter is placed against the bone.

Method of Anchoring a First Soft Tissue Portion to a Second Soft Tissue Portion

Another aspect provided herein, per FIGS. 11A-16 , is a first method of suturing a first soft tissue portion to a second soft tissue portion. In some embodiments, the method comprises: providing the second suturing system or third suturing system (e.g., comprising suture inserter device 2000 or 3000), piercing the soft tissue at a first side so as to be inserted through a first hole in the soft tissue (e.g., meniscus) with a needle (e.g., 610 or 620), per FIGS. 11A and 11B, and thereby inserting the first anchor 700A through the first hole in the insertion configuration, and exiting the soft tissue at a second side. With reference to FIGS. 12A-12B, the needle is translated within the housing lumen between the primary configuration and the secondary configuration (as described herein), such that the first anchor 700A remains on the second side of the soft tissue. In some embodiments, the first anchor 700A is pulled at least at an angle relative to a longitudinal axis of the needle (e.g., 610 or 620), such that the anchor 700A and corresponding anchor inserts are pulled against an angle of the first hole. Accordingly, in some cases, the anchor 700A will be refrained from passing through the first hole. In some cases, the anchor 700A remains in an insertion configuration. In some cases, the anchor 700A transitions from an insertion configuration to a deployed configuration (as described herein), and is thereby anchored to one side of the soft tissue (e.g., meniscus), while the needle translates away from the second side of the soft tissue. With reference to FIGS. 13A-13B, the second needle is inserted through another location of the soft tissue (or another soft tissue), thereby piercing the soft tissue and passing through a second hole in the tissue, thereby inserting the second anchor 700B through the second hole in the insertion configuration. With respect to FIGS. 14A-14B, applying tension to an end of the suture 720 enables the first anchor 700A and the second anchor 700B to transition from the insertion configuration to the deployed configuration. In some embodiments, the suture is tensioned while the second needle is inserted through the tissue portion. In some embodiments, the suture is tensioned after the second needle has been retracted and moved away from the soft tissue. With respect to FIG. 15 , the second needle is pulled out through the second hole while the second anchor 700B remains deployed and anchored to the tissue, thereby separating the second needle and suture insertion device from the suture 720. In some embodiments, with respect to FIG. 16 , the suture 720 is then trimmed.

In some embodiments, the suture anchor system 3000 is used, wherein instead of pulling out the second needle with the suture device, the second needle is transitioned from a primary configuration to a secondary configuration. In some embodiments, a diameter or width of the first hole and/or second hole in the soft tissue is at most about 3 mm, about 2 mm, or about 1 mm.

In some embodiments, the first portion of the soft tissue is a portion of a first soft tissue, and wherein the second soft tissue portion is a portion of a second soft tissue.

In some embodiments, a method of suturing a first soft tissue portion to a second soft tissue portion comprises: (a) receiving the third suturing system herein; (b) piercing the first soft tissue portion with the first needle in the primary configuration; (c) extracting the first needle from the first soft tissue portion; (d) translating the first needle within the first housing lumen to the first secondary configuration; (e) piercing the second soft tissue portion with the second needle; and (f) extracting the second needle from the second soft tissue portion.

In some embodiments, the method further comprises trimming the suture, tightening the suture, locking the suture, or any combination thereof. In some embodiments, step (e) is performed before step (d). In some embodiments, the method further comprises translating the secondary needle within the secondary housing lumen to the primary configuration, before or after step (f).

A method of anchoring to a bone, the method comprising: providing a suturing system comprising a. an anchor comprising: i. a suture having a first end and a second end; and ii. a plurality of anchor inserts disposed along a portion of the suture between the first end and the second end, the anchor configured to transition from an insertion configuration that is substantially linear to a deployed configuration that is at least partially nonlinear, wherein each of the plurality of anchor inserts comprise an independently defined shape and are linked together, and wherein the plurality of inserts comprise a leading anchor insert that is configured to be displaced via the suture or a deployment suture, so as to transition the anchor from the insertion configuration to the deployed configuration; and b. a suture inserter device comprising: i. a housing comprising a housing lumen and a housing shaft disposed therein, wherein the housing shaft is axially translatable; and ii. an inserter fork coupled to the housing shaft, wherein the inserter fork is axially translatable, via the housing shaft, between a distal position and a proximal position, inserting the inserter and the anchor into a hole partially in a bone hole of the bone, wherein the anchor is in the insertion configuration; applying proximal tension to the first end of the suture or the deployment suture to transition the anchor from the insertion configuration to the deployed configuration; and axially translating the inserter with respect to the housing shaft from the distal position to the proximal position.
 18. The method of claim 17, further comprising trimming the suture, tightening the suture, locking the suture, or any combination thereof.
 19. The method of claim 17, wherein the hole in the bone has a depth of less than about 35 mm.
 20. The method of claim 17, wherein an outer diameter of the housing is greater than the inner diameter of the hole.
